20120241478 | Ultrasonic Suspension Delivery System - An ultrasonic suspension delivery system is provided. The system includes an ultrasonic energy source and an ultrasonic resonating syringe electrically coupled thereto. The ultrasonic resonating syringe includes a barrel with a nozzle, and an ultrasonic resonating plunger slidingly displaceable within the barrel. The ultrasonic resonating syringe includes front and rear bodies, front and rear transducers, and front and rear horns. A support member or a transition member may also be included. | 09-27-2012 |
20100078496 | METHODS AND SYSTEMS FOR ULTRASONIC SPRAY SHAPING - New and improved ultrasonic spray shaping assemblies, components thereof, and methods for using the assemblies. An ultrasonic spray shaping assembly includes jet block and impact jet components to receive and redirect a single gas stream, whereby to use the single gas stream to shape an ultrasonic spray plume in a desired shape, particularly into a desired width of the plume. Modifications to the components, such as relative positioning, can be used to alter the shape of the spray plume. The present invention can be fabricated in a compact, lightweight design. It has many applications, including but not limited to, the deposition of flux onto a printed circuit board. | 04-01-2010 |
20090254020 | ULTRASONIC METHOD FOR ESTABLISHING AND MAINTAINING A LIQUID SUSPENSION DELIVERY SYSTEM THAT PREVENTS THE DISPERSED PARTICLES FROM PRECIPITATING OUT OF SUSPENSION - The present invention relates generally to a method and apparatus for applying wave energy of an ultrasonic frequency to agitate particles in a sample. The agitated sample is then delivered via a syringe or a resonating syringe plunger attachment of an applicator. More particularly, the present invention relates to establishing and maintaining a liquid suspension delivery system that prevents dispersed particles from precipitating out of suspension while the sample is delivered through to various applicators, such as resonating syringe plungers. | 10-08-2009 |
